4 Planet Earth Our solar system The sun, the center of our solar system, is a glowing gas ball made of hydrogen and helium. Its diameter is about 1.4 million kilometers. Inside the sun there is an unimaginably high pressure. It causes the smaller hydrogen atoms to fuse to form the larger helium atoms. A lot of energy is released, which the sun radiates in all directions. The sun is circumnavigated by planets at certain different distances. The planetary orbits are elliptical. Planets are cold celestial bodies. They do not send out any light themselves. But since they reflect the light of the sun, they appear as luminous points in the night sky. The planet closest to the Sun is Mercury, followed by Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. In addition to these eight large planets, the sun is orbited by many small planets (e.g. Pluto), so-called asteroids. Planet Earth Solar System Eight large planets and a multitude of small planets surround the sun. Hydrogen and helium are gases. Like all substances, gases also consist of the smallest particles, the atoms. Sun All celestial bodies which, like our sun, radiate energy and are therefore very hot and shine, are called suns or stars. elliptical oval; the orbits of all the planets in our solar system are very similar to a circle, i.e. weakly elliptical.
